Sažetak

The aim of the present study was to establish the protocol for micropropagation of blackberry cultivar ‘Reuben’. Using stereomicroscope, shoot tips were isolated from axillary buds and placed on medium (EM) to establish aseptic culture. The effect of different sugars in proliferation medium (PM) in the two variants: 30 g L-1 sucrose or 20 g L-1 glucose + 10 g L-1 sucrose was tested. In order to establish optimal constitution of cytokinins, in second experiment 5 treatments were tested: 6- benzylaminopurine (BAP) in concentration of 1 mg L-1 and 0.3 mg L-1 and meta-Topoline (mT) in the same concentrations, as well as a control hormone free medium. In vitro rooting was carried out in two experimental variants, on IAA added rooting medium and on hormone free medium. The greatest number of shoots/explant (2.6), but in the same time the shortest shoots, were produced on medium containing 1 mg L-1 BAP. Maximum shoots length was produced on medium containing 0.3 mg L-1 BAP or mT as well as on medium without hormones. The rooting percentage was higher (61%) on hormone free rooting medium. Acclimatization was very successful reaching 92% -95%, depending on rooting medium.
